5 Instructions
General Surface Prep
USE CHEMICAL-RESISTANT GLOVES, such as nitrile,
when handling product.
Surfaces must be structurally sound. Remove all grease, oil, dirt,
curing compounds, sealers, adhesives or any other contaminant that
would prevent a good bond. Glossy or painted surfaces must be
sanded, or abraded, and stripped of all contaminants. Concrete must
be cured 28 days and accept water penetration. Concrete must be free
of efflorescence and not subject to hydrostatic pressure. Concrete
slabs should have a coarse finish to enhance the bond. Plywood
flooring including those under resilient flooring must be structurally
soundand meet all ANSI and deflection requirements. For questions
about proper subfloor installation, call Technical Services. Smooth
concrete surfaces, existing glazed tile, terrazzo, or polished stone
should be scarified. Sheet vinyl must be well bonded and stripped of
old finish. Roughen the surface by sanding or abrading, then rinse and
allow to dry. Expansion joints should never be bridged with setting
material. Do not sand flooring materials containing asbestos. Ambient
temperatureshouldbemaintainedabove50°F(10°C)orbelow100°
F(38°C)for72hourstoachieveproperbond.
Bonding to Concrete Surfaces
Concrete or plaster must be fully cured and must accept water
penetration. Test by sprinkling water on various areas of the substrate.
If water penetrates, then a good bond can be achieved; if water
beads, surface contaminants are present, and loss of adhesion may
occur. Contaminants should be mechanically removed before
installation. Concrete must be free of efflorescence and not subject to
hydrostatic pressure. Concrete slabs should have a coarse finish to
enhance the bond. Smooth concrete slabs must be mechanically
abraded to achieve proper bond.
Bonding to Lightweight Cement and Gypsum Surfaces
Lightweight or gypsum based underlayments must obtain a minimum
2000 psi (13.8 MPa) compressive strength. The underlayment must be
sufficientlydryandproperlycuredtothemanufacturer’sspecifications
for permanent, non-moisture permeable coverings. Surfaces to be
tiled must be structurally sound and subject to deflection not to exceed
the current ANSI Standards. Surfaces shall be free of all grease, oil,
dirt, dust, curing compounds, waxes, sealers, efflorescence, or any
other foreign matter.

All Lightweight cement or Gypsum surfaces should be primed. with a
properly applied sealer or a primer coat of RedGard, consisting of 1
part RedGard diluted with 4 parts clean, cool water. Mix in a clean
bucket at low speed to obtain a lump free solution. The primer can be
brushed, rolled or sprayed to achieve an even coat. Apply the primer
coat to the floor at a rate of 300 ft2/gal (7.5 M2/L). Drying time
depends on site conditions, but is normally less than 1 hour. Extremely
porous surfaces may require 2 coats. At this point, RedGard can be
applied to the primed lightweight or gypsum based surface. Refer to
the individual product data sheet or packaging directions for application
instructions. Expansion joints must be installed in accordance with local
building codes and ANSI/TCNA guidelines. Refer to TCNA EJ171.
Bonding to Plywood Surfaces
Plywood floors, including those under resilient flooring, must be
structurally sound and must meet all ANSI A108.01 Part 3.4
requirements. Maximum allowable deflection: L/360 tile L/720 stone.
See TCNA F150-13 tile installations, TCNA F141-13 and F250-13 for
stone. For questions about proper subfloor installation requirements,
callCustom®TechnicalServices.
Bonding to Backerboards
As an alternative to an additional layer of plywood, WonderBoard Lite
backerboard may be installed over plywood subfloors for ceramic tile
installations. Refer to TCNA F144-13 tile installations and TCNA F-250-
13forstone.CallCustom®TechnicalServiceswheninstallingnatural
stone over plywood subfloor.
Bonding to Existing Surfacing Material
Existing Ceramic Tile, Resilient Flooring or Plastic Laminates: Resilient
flooring or plastic laminates must be well bonded, as well as clean and
free of all contaminates. Roughen the surface by sanding or scarifying;
rinse and allow to dry. Do not sand flooring that contains asbestos. For
existing well bonded ceramic tile, mechanically abrade the surface.
Rinse and allow to dry. When sanding, an approved respirator should
be used.
Bonding to Cutback Adhesive
Adhesive layers must be removed, as they reduce mortar bond
strength to cement surfaces. Use extreme caution; adhesives may
contain asbestos fibers. Do not sand or grind adhesive residue, as
harmful dust may result. Never use adhesive removers or solvents, as
they soften the adhesive and may cause it to penetrate into the
concrete. Adhesive residue must be wet-scraped to the finished
surface of the concrete, leaving only the transparent staining from the
glue. To determine desirable results, do a test bond area before
starting. Refer to the RFCI Pamphlet, "Recommended Work Practices
for Removal of Resilient Floor Coverings", for further information.
Movement Joint Placement
Movement joints are required for perimeters and other changes of
plane in all installations. Expansion joints and cold joints, as described
in ANSI A108.01, should never be bridged with setting material. They
must be brought through the tile work and filled with an appropriate
elastomericsealant,suchasCustom's®100%Silicone.Contact
Custom's®TechnicalServicesforthepropertreatmentofcontrolor
saw cut joints. Refer to TCNA EJ171, F125 and F125A.
Mixing Ratios
Mix 5.75 - 6 qts (5.4 - 5.7 L) clean water per 30 lb (13.6 kg) bag of
mortar.
Mixing Procedures
Mix by hand or use a low 150-200 RPM speed 1/2" (13 mm) drill to
achieve a smooth, paste-like consistency. Let the mixture slake or
stand 3 minutes; stir again and use. Stir occasionally, but do not add
more water. When properly mixed, troweled ridges will stand without
slump.
Application of Product
Installation must conform to ANSI A108.5. Use a properly-sized notch
trowel to ensure proper coverage under tiles. Using the flat side of the
trowel, apply a skim coat of mortar to the surface. With the notch side
ofthetrowelheldata45°angle,applyadditionalmortartothe
surface, combing in one direction. Press the tile firmly into place in a
perpendicular motion across ridges, moving back and forth. The
perpendicular motion flattens ridges and closes valleys, allowing
maximum coverage. With some tile, back-buttering is advisable. Adjust
the tile promptly and beat it in with a beating block and rubber mallet.
Periodically pull up a tile and check the back to ensure proper adhesive
coverage. If the material has skinned over (not sticky to the touch),
recomb with the notch trowel; if too dry, remove and replace the dry
material with fresh material. Thin-Set Mortar should not be used to fill
low spots in the flooring. Mortar thickness should be less than 3/4"
when beat in.
Curing of Product
Curing time is affected by ambient and surface temperatures and
humidity. Use the following as a guideline. Allow 3 hours before
grouting, 4 hours before light traffic, and 3 days before heavy or
vehicular traffic. Before exposure to heavy or vehicular traffic, assure
assemblyisrated“HeavyorExtraHeavy”perTCNAService
Requirements. As necessary, use plywood or other load distributing
protection when moving heavy equipment across tiled assembly.
Submerged installations must cure for 14 days before filling with
water.
Cleaning of equipment
Clean with water before the material dries.
Storage
Store in a cool dry area.
Health Precautions
This product contains Portland cement and free silica. Avoid eye
contact or prolonged contact with skin. Wash thoroughly after
handling. If eye contact occurs, flush with water for 15 minutes and
consult a physician. Do not breathe dust; wear a NIOSH approved
respirator.
Conformance to Building Codes
Installation must comply with the requirements of all applicable local,
state and federal code jurisdictions.
